> ## Documentation Index
> Fetch the complete documentation index at: https://phaseo.app/docs/llms.txt
> Use this file to discover all available pages before exploring further.

> ## Agent Instructions
> Phaseo Gateway base URL: https://api.phaseo.app/v1. Send `Authorization: Bearer $PHASEO_API_KEY` with every request.
> Model IDs look like `provider/model`, for example `openai/gpt-6-astra`. Do not guess IDs: list them with `GET /v1/models` or check https://phaseo.app/models. `phaseo/free` routes to an available free model and needs no wallet balance.
> For new text integrations prefer `POST /v1/responses`. `POST /v1/chat/completions` (OpenAI format) and `POST /v1/messages` (Anthropic format) suit existing code.
> The full API contract is https://phaseo.app/docs/openapi/v1/openapi.yaml. Official SDKs: `@phaseo/sdk` (TypeScript) and `phaseo` (Python), plus Go, C#, PHP, Ruby and Rust.
> Search these docs over MCP at https://phaseo.app/docs/mcp, and install Phaseo skills with `npx skills add https://phaseo.app/docs`. If a page is wrong or out of date, report it with the MCP `submit_feedback` tool.
> Manage Phaseo accounts with the `phaseo` CLI (`npm install -g @phaseo/cli`, then `phaseo login` or `phaseo login --device-code`), the `/v1` Management API or the MCP server at `https://mcp.phaseo.app/mcp?access=manage`. Do not send users to the dashboard for account tasks. A person is still needed for sign-up, approving a sign-in, paying the first top-up on the checkout link that `phaseo credits add` returns when no card is saved, confirming each saved-card top-up from the emailed link, and account security (password, MFA, passkeys). Create API keys with `phaseo keys create --name <name> --json`; never guess one. Credit top-ups need `phaseo login --scopes billing:write` first. Task map: https://phaseo.app/docs/v1/developers/manage-from-an-agent.md.

API & SDKs

* **Breaking:** The TypeScript, Python, Go, C#, Java, PHP and Ruby SDKs `3.0.0` return the Phaseo model catalogue format from the models endpoint; update code that reads model fields ([#1280](https://github.com/phaseoteam/Phaseo/pull/1280)).
* The SDKs `3.0.0` add management methods for API and management keys, guardrails, budgets, presets, members, SSO and SCIM, notifications and Private Models ([#1280](https://github.com/phaseoteam/Phaseo/pull/1280), [#2422](https://github.com/phaseoteam/Phaseo/pull/2422)).
* Phaseo CLI `0.3.0` sets up coding agents such as OpenCode, and runs Cline, Kilo Code, oh-my-pi, Muse Code and MiniMax Code through Phaseo; see [Phaseo CLI](https://phaseo.app/docs/v1/guides/integrations/phaseo-cli.md) ([#2325](https://github.com/phaseoteam/Phaseo/pull/2325), [#2336](https://github.com/phaseoteam/Phaseo/pull/2336), [#1280](https://github.com/phaseoteam/Phaseo/pull/1280)).

**September 15, 2026**

Product

* Chat, model and provider privacy rules now come only from the active workspace, including personal workspaces, and workspace privacy settings save again ([#2400](https://github.com/phaseoteam/Phaseo/pull/2400), [#2403](https://github.com/phaseoteam/Phaseo/pull/2403)).
* Turning on Auto Top-Up without two-factor authentication requires a typed confirmation, and existing setups without it show a warning ([#2401](https://github.com/phaseoteam/Phaseo/pull/2401)).
* Buying credits through Stripe checkout works again; before, checkout failed before reaching Stripe ([#2405](https://github.com/phaseoteam/Phaseo/pull/2405)).

API & SDKs

* The Terraform provider `0.1.0` manages API keys, guardrails, provider credentials, SCIM group mappings and observability destinations, and reads models, providers and credits ([#2164](https://github.com/phaseoteam/Phaseo/pull/2164), [#2396](https://github.com/phaseoteam/Phaseo/pull/2396)).
* API key and management key limits are counted separately, and only active, unexpired keys count toward them ([#2399](https://github.com/phaseoteam/Phaseo/pull/2399)).

**September 14, 2026**

Product

* Chat adds a navigation rail with a marker for each turn, so you can jump through long conversations ([#2385](https://github.com/phaseoteam/Phaseo/pull/2385)).
* The Chat model picker disables models your guardrails block, adds a **Hide Unavailable** filter, and Ctrl- or ⌘-click adds models to a comparison ([#2389](https://github.com/phaseoteam/Phaseo/pull/2389)).
* Changing your account country saves again; before, the change failed ([#2392](https://github.com/phaseoteam/Phaseo/pull/2392)).

**September 13, 2026**

Product

* Chat lets you choose Standard, Priority or Flex for each model and sends Priority and Flex as `service_tier` ([#2357](https://github.com/phaseoteam/Phaseo/pull/2357)).
* Provider cards on model pages chart uptime, latency and throughput hour by hour for the last 60 hours, marking hours with no data ([#2361](https://github.com/phaseoteam/Phaseo/pull/2361)).
* Chat shows reasoning as it streams, and each reply's details show the gateway-measured throughput, output tokens and service tier ([#2359](https://github.com/phaseoteam/Phaseo/pull/2359), [#2367](https://github.com/phaseoteam/Phaseo/pull/2367)).
* Model deprecation alerts reach the workspace's notification destinations, and deprecation warnings recommend a replacement model; see [Model Deprecation and Retirement](https://phaseo.app/docs/v1/guides/model-retirement.md) ([#2136](https://github.com/phaseoteam/Phaseo/pull/2136)).

API & SDKs

* Requests without `service_tier`, or with `service_tier: "default"`, use Standard routes, and Flex-only offers serve only requests that ask for `flex`; see [Service Tiers](https://phaseo.app/docs/v1/guides/service-tiers.md) ([#2356](https://github.com/phaseoteam/Phaseo/pull/2356), [#2354](https://github.com/phaseoteam/Phaseo/pull/2354)).
* Requests that use gateway-managed tools stream each model turn's text and tool calls as they arrive instead of all at once at the end ([#2360](https://github.com/phaseoteam/Phaseo/pull/2360), [#2363](https://github.com/phaseoteam/Phaseo/pull/2363)).

**September 11, 2026**

Product

* **Settings -> API Keys** can search by key name or by a pasted full key, which stays masked ([#2344](https://github.com/phaseoteam/Phaseo/pull/2344)).
* Model pages show provider latency, throughput and uptime from a provider's first request instead of after 20 requests, and chart cache rate per provider ([#2339](https://github.com/phaseoteam/Phaseo/pull/2339), [#2341](https://github.com/phaseoteam/Phaseo/pull/2341)).

Product

* **Settings -> Billing & Credits** shows an active Enterprise subscription beside usage credits and manages it through the Stripe portal ([#2252](https://github.com/phaseoteam/Phaseo/pull/2252)).
* Credit purchases link to their Stripe receipt instead of an invoice ([#2256](https://github.com/phaseoteam/Phaseo/pull/2256)).
* The API keys list hides expired keys by default, sorts enabled keys first, adds status filters and moves bulk actions to a floating bar ([#2261](https://github.com/phaseoteam/Phaseo/pull/2261)).
* Testing a key in Settings accepts current `phaseo_v1_sk_` keys; before, newly created keys failed the test ([#2251](https://github.com/phaseoteam/Phaseo/pull/2251)).

API & SDKs

* `phaseo:web_search` accepts `engine: "tinyfish"` to search with TinyFish, with language hints, result pages and the shared domain filters; see [Web Search Server Tool](https://phaseo.app/docs/v1/guides/server-tools/web-search.md) ([#2124](https://github.com/phaseoteam/Phaseo/pull/2124)).
* OAuth sign-in from native apps that use a loopback callback on a random port, such as coding agents connecting to the MCP server, no longer fails with `invalid_client` ([#2129](https://github.com/phaseoteam/Phaseo/pull/2129)).
